Rapeseed plantation biodiesel production systems require the transportation of goods, like raw materials, machines and tools, and products between various conversion stages of agricultural as well as industrial subsystems. Each transportation step requires the consumption of some energy. This consumption decreases the net amount of energy delivered out of the biofuel production system, and consequently decreases the energetic efficiency of the system. The majority of studies on biofuel sustainability are done by means of the LCA method with the use of a data average for some region and period of time. Such analyses do not reveal the possible causes of the conclusions determined. The present work deals with computer modelling of the influence of the energy consumed on those transport routes on the energetic efficiency of the production system. The model enables determination of the effects caused by changes introduced to technological parameters. The effects caused by variation of fuel consumption, the load capacity of transportation means, size of plantation, distribution and sizes of individual fields, distances between fields, plantation yield, and finally the distance between the plantation and the industrial facility are studied using the numerical model developed earlier. This approach is aimed towards identifying the reasons for the behavior of a system controlled by many somewhat coupled variables.

Biofuel is one of alternative fossil fuel, in which the raw materials come from biological resources.One of the raw materials for biofuel production is microalgae. Microalgae grows rapidly, does notcompete with food for humans, and needs small areas to cultivate. Utilization of microalgae forbiofuel research nowadays is focusing on biodiesel production, but actually microalgae can beused to produce other biofuels such as bioethanol. The carbohydrate content of the microalgaecan be converted into glucose and fermented into alcohol. Carbohydrate content of the microalgaeis about 5.0–67.9%, which could produce bioethanol up to 38%. A harmony between bioethanoland biodiesel production from microalgae is needed for the optimum utilization of microalgae.Bioethanol production from microalgae can be done using de-oiled microalgae.

In order to optimize the performance of transportation works for the transportation of raw materials for the production of biodiesel fuel, the article examines the technology when oil from oilseeds is obtained at the processing points where they are grown. The resulting oil is transported to a biodiesel production plant. The methodological bases for calculating the optimum distance from oilseed grain storage sites to a mechanized oil production point are presented. Possible ways of the efficiency improving of production of biofuel at the stage of the planning are presented. Methodical bases of calculation of distance to mechanized points for biofuel production are given. A formula for determining the optimum capacity of an item for the processing of oil seeds and for obtaining raw materials for the production of biofuels has been derived. It is established that optimum transportation distance of rape is 14,4 km, productivity of the rapeseed oil processing plant is 21280 tons/year and for 25% of the oil yield 5320 tons of biofuel raw materials can be obtained, when the total overhead costs are Zv = 360000 UAH / year; specific costs of transportation of raw materials сp = 2,6 UAH/ (тkm); yield of oilseed rape = 1 t / ha (100 t / km2); the density of the placement of fields a = 0.4. The developed method can be used to calculate the location, performance of points for the manufacture of briquettes or pellets. The direction of increasing the efficiency of biodiesel production at plants at the stage of their planning is to determine the optimal annual productivity of the plant, taking into account transport costs for the transportation of raw materials - oil. The optimum distance of transportation of oil and productivity of the plant for biodiesel production is established for the cost of transportation - 2.6 UAH / t • km, overhead costs 13000000 UAH, direct costs for the production of 1 ton of biodiesel fuel - 25000 UAH Therefore, the optimal distance of transportation of oil for the production of biofuels - 101 km, the capacity of the plant - 58923 tons. The dependence of the cost of production of biodiesel fuel on the distance of transportation of oil is calculated: for distance to plant 40 km – the cost of biofuel production – 25596 UAH/t, for 60 km – 25496 UAH /t, for 80 km – 25462 UAH /t, for 100 km – 25459 UAH /t, for 120 km – 25471 UAH /t, for 140 km – 25493 UAH /t. The proposed method provides an opportunity to determine the optimum productivity of the plant for the processing of organic raw materials into biofuels, taking into account the distance of its transportation at the design stage. Key words: biodiesel, economic efficiency, production optimization, direct costs, overhead costs.

Reduction Of Co2

The aim of the article is to assess the dynamics of the development of biofuels production from agricultural raw materials and the share of biofuels in the consumption of the most important agricultural raw materials with particular regard to the situation in Poland. Data used in the study are derived from OECD statistics as well as CSO statistics. The analysis covered the period from 2005 to 2016. The biofuel production on a global scale is increasingly competing with food production. Between 2002 and 2004, about 2% of harvested cereals were allocated to biofuels, and in 2016 it was almost 8%. For oil plants, this level reached 15%. Following a dynamic growth in biofuel production between 2005 and 2010, the growth slowed down considerably - to the level of 7% annually for biodiesel and 4.6% annually for bioethanol production. For the years 2017-2025, a growth rate of about 1% per year is anticipated. The slowdown in production growth is due to the reduction of political support for the development of the production of biofuels from first generation raw materials. Their production leads to competition for land resources with food production, but it has also been found to be characterized by relatively low environmental performance, including a low impact on the reduction of CO2 emissions. It is necessary to develop the production of second generation biofuels which now account for only about 7% of the production of liquid biofuels. Biofuels in Poland are produced from cereals and rapeseed oil. The production of biofuels in Poland increased from 180 million litres in 2005 to 1.2 billion litres in 2015. 1.3% of arable land was used for bioethanol production and 3.5% for biodiesel production. Total production of raw materials for biofuels was conducted on 5% of arable land in Poland. 2% of cereals and 60% of the rape crop were consumed for the production of biofuels. Under Polish agriculture conditions, biofuels production does not compete with food production yet.

The study gives an overview of raw materials and biofuel generation, markets, production, and regulation. The major aim of this study was to reveal the impacts of biofuel production on international commodity trade. According to the results of the country-level regressions, the export of corn and sugar cane have generally negatively impacted ethanol production. This effect was positive at the global level which indicates that some of the imported raw materials are used for ethanol production. Although the explanatory power of the models was relatively high (from 0.35 (EU) to 0.94 (USA)), none of models proved to be significant, even at the 10% level. These values were higher for the biodiesel models (from 0.53 (USA) to 0.97 (Brazil)) and the EU model results were significant at the 5% level. The export of raw materials had a positive impact on biodiesel production. This implies that some part of the biodiesel was produced from the imported raw materials. The export of processed products (different oils) had a negative impact on biodiesel production, as they are normally used for other purposes.

The aim of the study was to determine the possibility of using the unconventional vegetable oils for the biofuel production. The research material were cold-pressed oils from the seeds of milk thistle, hemp and evening primrose. After conducting the initial physicochemical characteristics of oil samples, including the determination of sulphur content, acid number, viscosity at 40°C, density at 15ºC, oxidation stability and fatty acid composition, analysed oils have been subjected to the transesterification process. The roduced methyl esters were further characterized by the above-mentioned features. Additionally, the temperatures of cold filter plugging point, cloud point and flash point were determined. On the basis of the conducted analyses it was demonstrated that the obtained oils, due to the high, far in excess of acceptable, values of the viscosity and density, and too low oxidative stability could not be used as a pure fuel. A similar conclusion was formulated in case of the produced methyl esters.

Improvement of production systems of the organization is carried out through the introduction of quality management systems, changes in the model of production organization, the use of modern approaches to improve product quality and customer satisfaction. Measurement, evaluation and analysis of the production system allows to set the direction of activity to improve production processes and to develop activities aimed at ensuring the effectiveness of the whole system. The production system is an open system, it is connected and exchanged with the external environment information, resources, etc. the production system is Called the operating system, which consists of three subsystems: processing subsystem, directly related to the technological processes of raw materials and semi-finished products conversion into finished products; support subsystem, which performs auxiliary functions necessary for the implementation of the main technological processes; planning and control subsystems that receive and process information from the internal and external environment of the organization. The task of building an automated information system is connected with the need to integrate with the subsystem of data collection and analysis, visual representation of information for decision-making at all levels. Building an information management system of the production system is impossible without a powerful infrastructure, without a single information system support and process control. The proposed information system will help to automate the processes of management of the organization, quickly form the strategic and tactical goals of the organization. Within a given period of time, data will be collected and analyzed from the internal and external environment, timely analysis of deviations of the values of indicators from the planned values. The results of information processing will be timely visualized both for each employee and the production system of the organization as a whole.
